Abstract
A method of repairing a metallic component is disclosed. The method may include machining away a damaged first portion of the component, and machining away a second portion of the component adjacent the damaged first portion, the second portion being an area that would be subject to distortion resulting from solidification of molten weld material added to repair the damaged first portion. The method may also include inserting a dam made of a high-temperature-resistant material adjacent the machined away second portion to contain molten weld material added to the machined away second portion. Oxy-fuel welding may be performed to at least partially fill the machined away damaged first portion of the component and the machined away second portion of the component, and final machining of the welded portions may be performed.
